MPM54313

The MPM54313 is a triple 3A, fully integrated power module with an I²C interface. The device offers a complete power solution with integrated on/off sequencing, configurable soft start (SS), compensation, and various protection thresholds. Constant-on-time (COT) control provides fast transient response, while the 1MHz switching frequency (f_SW) greatly reduces the passive component size.

The output voltage (V_OUT) can be adjusted via the I²C bus or can be preset by the multiple-time programmable (MTP) memory. The on/off sequence can also be configured via the MTP or controlled by the online I²C bus. The device offers configurable active voltage positioning (AVP), which generates a droop voltage that allows for three parallel outputs with passive current balancing. For active current balancing, two of the outputs can operate in parallel up to 6A in interleaving mode.

Full protection features include under-voltage lockout (UVLO) protection, over-current protection (OCP), over-voltage protection (OVP), under-voltage protection (UVP), and thermal shutdown. The MPM54313 requires a minimal number of external components, and is available in a compact BGA (8mmx9mmx2.58mm) package.
